How many weeks are you and what size is your fetus? (Or at the time of your last ultrasound) I think there's always a question about what' s "normal" and it would be really interesting (and calming....) to see just how different every woman and every fetus is. At my 15 week ultrasound my fetus was 8.11 cm head to rump and I can't remember what it weighed. How 'bout you?
